slack – Split message by lines

I have a list of things which i want to send to my team, and i want to each team member add reaction to thing which he/she is working on.

For now i send about 10 messages one by one, and teammates add reactions, is there any possibility to send one message and split it by lines to allow my teammates add reactions to each line?

in future i want to set slackbot reminder to send list of things each week, but i don’t want to my team have 10+ notifications each monday and i’m looking for some smart way to do it
